Nikon V1 Optics
The Nikon V1 is sold in three different kits, which differ in their choice of bundled lenses. The most affordable of these includes a 1 NIKKOR 10-30mm f/3.5-5.6 VR zoom lens, at a suggested retail price of around US$900. Alternatively, there are two twin-lens kits, each of which supplements the 10-30mm VR zoom with either a 10mm f/2.8 pancake lens or a 30-110mm f/3.8-5.6 VR zoom lens. Both twin-lens kits are priced at around US$1,150. The optical tests below apply to the main 10-30mm kit lens.
All three kit lenses feature 40.5mm filter threads, a nice touch since that means they can all share the same filters, and their lens caps are interchangeable. The trio also have 7-bladed, rounded apertures for pleasing bokeh, and their front elements don't rotate when focusing or (for the zooms) when adjusting focal length. (The zooms are internal focusing, and the prime is rear-focusing.) In all three cases, there's no physical focus ring, though, and so manual focusing must be achieved from the camera body. Both zooms have collapsing designs that greatly reduce overall size, and which lock in both the retracted and extended positions to prevent accidents. All three lenses are available in a choice of colors to match the Nikon J1 camera body. Choices for the trio include black, white, silver, and red, and the zooms are both available in pink, although this isn't an option for the 10mm prime. Only the black version is bundled with the Nikon V1 in the US.
Optical construction of the 10-30mm kit lens consists of 12 elements in 9 groups, with 3 aspherical elements. Minimum focusing distance is 20cm or 7.9 inches for a maximum magnification ratio of 0.57x or 1:1.75 equivalent at 30mm. Optical zoom ratio is 3x, with rotary zoom action. Length is 42mm or 1.7 inches when the lens is retracted, while maximum diameter is 57.5mm or 2.3 inches. Weight is about 115 grams or 4.1 oz.
For the 30-110mm kit lens, the optical formula is 18 elements in 12 groups, including two extra-low dispersion glass elements. Minimum focusing distance is 1m or 3.3 feet, and optical zoom ratio is 3.7x, with rotary zoom action. Length is 61mm or 2.4 inches when the lens is retracted, while maximum diameter is 60mm or 2.4 inches. Weight is about 175 grams or 6.2 oz. List pricing for this lens is US$250 when purchased separately, and it effectively costs the same when bundled in a twin-lens kit.
Finally, the remaining kit lens (and the only 1-mount prime to date) is the 10mm. Its optical formula is 6 elements in 5 groups, including two aspherical elements. Minimum focusing distance is 20cm or 7.9 inches. Length is 22mm or 0.9 inches, while maximum diameter is 55.5mm or 2.2 inches. Weight is about 77 grams or 2.7 oz., making this by far the smallest and lightest 1-mount lens yet announced. List pricing for this lens is US$250 when purchased separately, and again, it costs the same when bundled in a twin-lens kit.
Nikon's new 1 System cameras debut a new mount dubbed the 1-mount, designed to accommodate a CX-format image sensor and the reduced backfocus distance of a mirrorless design. As noted, all Nikon V1 kits in the US market include a 10-30mm f/3.5-5.6 stabilized zoom lens. This lens will yield 35mm-equivalent focal lengths ranging from 27 to 81mm, due to the sensor's 2.7x "crop factor". Two other optional 1-mount kit lenses were announced alongside the Nikon V1: a pancake prime, and a stabilized zoom. Starting with the prime, the 1 NIKKOR 10mm f/2.8 pancake prime lens offers a 27mm equivalent focal length, at a price of approximately US$250. For the zoom, the 1 NIKKOR VR 30-110mm f/3.8-5.6 lens will provide focal lengths from 81-297mm equivalents, and carries a pricetag of approximately US$250.
Finally, the 1 NIKKOR 10-100mm f/4.5-5.6 PD-ZOOM lens is the only 1-mount lens that's not available in a kit, and will offer an even wider 27-270mm equivalent range. It's clearly going after a different market, with a US$750 list price. This lens has a Power Drive zoom motor, voice coil AF motor, and Vibration Reduction system that are all said to be silent, making them well-suited to movie capture. The optical formula is 21 elements in 14 groups, including two aspherical and three extra-low dispersion glass elements. Minimum focusing distance is 30cm or 1.0 feet at wide angle, and 85cm or 2.8 feet at telephoto, while the optical zoom ratio is 10x. Length is 95mm or 3.7 inches, and maximum diameter is 77mm or 3.0 inches. Weight is about 515 grams or 18.2 oz, making this by far the largest and heaviest 1-mount lens.
This last model is Nikon's first power-zoom lens model. Power zooms are something that's come back into fashion of late, thanks to the rise of video capture in interchangeable-lens cameras. Mechanical zooms make it harder to adjust the focal length without shaking the camera during video capture, where a power zoom can make it relatively easier to do so. Panasonic recently announced a selection of power zoom lenses for its mirrorless cameras, and Nikon becomes the second system camera manufacturer to identify (and answer) videographers' needs in this area.
In addition to the dedicated 1-mount optics, a Nikon FT-1 F-mount adaptor will be offered for the V1, allowing the camera to accept F-mount lenses. Autofocus and autoexposure are fully supported with Nikkor AF-S lenses. Pricing and availability for this item have yet to be disclosed.
All current 1-mount zooms, including both the 10-30mm and 30-110mm kit lenses, include Nikon's "VR" (Vibration Reduction) optical image stabilization, which the company states offers up to 3 stops of correction to combat blur from camera shake. That means you can shoot at shutter speeds 8x slower than you can normally hand-hold without VR. Image stabilization comes in very handy for low-light shooting without a tripod, especially at telephoto focal lengths where camera motion blur is magnified, and where the lens is "slower" at f/5.6 (captures less light) versus wide angle at f/3.5 for the 10-30mm, f/3.8 for the 30-110mm, and f/4.5 for the 10-100mm lens.
An option in the Shooting menu allows image stabilization to be enabled or disabled, for lenses that support the function. The same option also lets you select between the Normal mode, which is suitable for levels of shake you'd expect when standing still, and an Active mode (if supported by the lens, as both kit zooms do), which provides a greater range of correction suited to shooting from a moving vehicle or while walking.
The Nikon V1's focus "servo" modes include Single AF (AF-S) which locks focus when the shutter button is half-pressed, Continuous AF (AF-C) which focuses continuously when the shutter button is half-pressed, Full-time AF (AF-F) which focuses continuously without having to half-press the shutter, Auto-select AF (AF-A) which automatically switches between AF-S and AF-C depending on if the subject is still or moving, and of course Manual focus (MF). In AF-C and AF-F modes, the shutter can be released whether or not the camera is able to focus, but in AF-S and AF-A modes, the subject must be in focus for the shutter to release.
The Nikon V1's hybrid AF system is swift. (We measured only 0.097s lag with Single-point AF -- that's faster than almost all professional DSLRs we've ever tested!) The speed of the AF system comes thanks to the fact that, unlike competing mirrorless cameras which rely solely on contrast detection to determine focus, the Nikon V1 has a hybrid system that combines both phase-detection and contrast-detection capability from the imaging sensor. The detection mode is chosen automatically as appropriate to the shooting conditions, and a generous array of 73 phase detection AF points are available.
The Nikon V1 offers three AF-area modes: Auto-area, Single-point, and Subject tracking. Nikon specifications state that 135 focus areas are available in Single-point AF mode, and 41 focus areas in Auto-area AF mode. We're not sure how the 135 and 41 figures relate to the 73 phase detect points and are currently seeking more information on the V1's hybrid AF system.
To help with focusing on nearby subjects in low ambient lighting conditions, the Nikon V1 includes an AF assist lamp which can be disabled in the Shooting menu.
The Nikon V1 vibrates its sensor's low-pass filter to remove dust each time the camera is turned on or off. Operating the camera controls before cleaning is complete interrupts this process. Since the V1's imager needs to be exposed for full-time live view, dust can be more of an issue than with a DSLR employing a mechanical shutter that is normally closed. Since we haven't yet seen an automatic system capable of removing all contaminants, users will eventually have to either learn how to clean their sensor, or send the camera in for cleaning.
Nikon V1 Optical Test Results
Kit Lens Test Results
A typical 3x kit lens zoom range, with good performance.
|10mm @ f/8||30mm @ f/8|
As mentioned above, the Nikon V1 is offered with the 1 Nikkor 10-30mm f/3.5-5.6 VR kit lens, possessing a typical optical zoom range of about 3x. The 35mm equivalent focal range is about 27-81mm, because of the V1's 2.7x "crop factor". Sharpness and contrast across most of the frame are quite good at 10mm and f/8, however there's moderate chromatic aberration and strong blurring visible in the extreme corners. Results at full telephoto are excellent with very good sharpness and contrast across the frame at f/5.6, and lower levels of chromatic aberration.
A small macro area (for a CSC kit lens), with good detail in the center.
|Macro with 10-30mm kit Lens
30mm @ f/8
The Nikon V1's macro performance will of course depend entirely on the lens in use. With the 10-30mm VR kit lens set to 30mm, the Nikon V1 captured a relatively small (for a non-macro CSC lens) minimum area measuring just 2.11 x 1.41 inches (54 x 36 millimeters). Detail was quite good but slightly soft in the center, though corners were quite soft. (Most lenses have some softening in the corners at macro distances.) Since the Nikon V1 does not come with a flash, we don't have our usual Macro with Flash results here.
Slightly higher than average barrel distortion at wide-angle, but almost no distortion at telephoto from the 10-30mm VR kit lens.
|Barrel distortion at 10mm is 0.9 percent|
|Pincushion distortion at 30mm is negligible|
The 1 Nikkor 10-30mm VR lens produced about 0.9 percent barrel distortion at wide-angle, which is slightly above average and noticeable in some of its images. At the telephoto end, there's hardly a pixel's work of pincushion distortion, which is much lower than average and obviously not noticeable. Geometric Distortion is the tendency for the lens to bend straight lines outward (like a barrel -- usually at wide-angle) or inward (like a pincushion -- usually at telephoto).
Surprisingly for the size of the lens, the Nikon V1 and J1 do not apply any geometric distortion correction to its JPEGs taken with this lens, as uncorrected RAW files have the same amount of distortion. We're used to seeing very strong barrel distortion from most Micro Four Thirds kit lenses at wide-angle, often on the order of 2-3%, which is automatically reduced in-camera and by most RAW converters. Not so for the 1 Nikkor 10-30mm kit lens. Nikon has managed to keep geometric distortion low enough that automatic in-camera correction is not essential, though some users may still want to correct the 0.9% barrel distortion at wide-angle in an editor for critical applications such as architectural photography.
Chromatic Aberration and Corner Sharpness
Moderately high chromatic aberration at wide-angle, moderate at telephoto. Mild to strong softening in the corners at wide-angle, but better corner sharpness at telephoto.
|10mm @ f/3.5: Lower right
C.A.: Moderately high
Softness: Very soft
|10mm @ f/3.5: Center
|30mm @ f/5.6: Lower right
C.A.: Moderate but dull
Softness: Somewhat soft
|30mm @ f/5.6: Center
C.A.: Very low
Chromatic Aberration. Chromatic aberration in the corners with the Nikon V1's 10-30mm kit lens is pretty evident (we'd call it on the high side of "moderate") at both wide-angle (10mm) and telephoto (30mm) settings. At wide-angle, it's brighter and therefore much more noticeable than at full telephoto. Color fringing is still somewhat evident in the center at wide-angle, but very low in the center at full telephoto. It's interesting to note that the V1 doesn't remove CA from its JPEGs as do more recent Nikon DSLRs, or at least it doesn't do as good a job. The bundled Nikon View NX 2 software is however quite effective at automatically suppressing CA when used to convert the V1's RAW files.
Corner Softness. Wide-open at full wide-angle, all four corners were softer than the center. The right-hand-side corners show more blurring than the left, with the bottom right being the softest. On the left side, softness was limited to extreme corners, and the center of the image was quite sharp. At full telephoto all four corners were actually pretty sharp, though contrast wasn't very good making the corners look soft. The center was quite sharp and contrasty.
Shading. Some minor vignetting or corner shading is, as can be seen by the slightly darker corner crops.
|10mm @ f/8: Lower right
C.A.: Moderately high
|10mm @ f/8: Center
|30mm @ f/8: Lower right
C.A.: Moderate but dull
Softness: Fairly sharp
|30mm @ f/8: Center
C.A.: Very low
"Stopped-down" to f/8, sharpness in the corners improved at wide-angle, though extreme corners were still somewhat soft. Performance at telephoto also improved with much better contrast in the corners. CA remained about the same as f/5.6, while vignetting improved.
Overall, a good performance for a kit lens.
Nikon V1 Viewfinder
Viewfinder Test Results
Very good accuracy from the electronic viewfinder and LCD monitor.
10mm, LCD Monitor
30mm, LCD Monitor
In record mode, the Nikon V1's electronic viewfinder and LCD monitor both provided slightly above 99% coverage at both wide-angle and telephoto when using the 10-30mm kit lens, which is very good.
The images above were taken from our standardized test shots. For a collection of more pictorial photos, see our Nikon V1 Photo Gallery.
